All boys in childhood dream of blowing up something or shooting something out of it. With what enthusiasm the children look at the explosions of firecrackers and firecrackers on New Year's Eve, how they dream of blowing them up on their own! But all this was bought in a store and of rather dubious quality. That is why we offer you some practical advice on how to make a rocket launcher for your child yourself and not worry about his safety in the future.
It is necessary
- What should be prepared for work:
- - colored or white A4 paper;
- - two round small sticks with a diameter of 1, 5 and 30 cm in length the first and a diameter of 1 and, respectively, 1 cm long - the second;
- - glue, if possible PVA;
- - confetti, bought in a store or made by yourself, or small ribbons of paper;
- - a paraffin candle;
- - an elastic band with a length of at least 200 cm;
- - threads.
Instructions
Step 1
So how to make a rocket launcher.
Take a long stick.
Rub this stick with a candle. This is required so that when gluing the paper does not stick to the stick and can be easily removed from it.
Lubricate the paper with glue on one side.
Make a paper tube by wrapping it around the stick several times. The wall thickness of your rocket launcher should be approximately 4mm.
Step 2
Remove the resulting tube from the stick.
Dry the resulting part.
Check if the stick can move freely inside the tube.
Step 3
Take a stick and a rubber band.
Insert the elastic into the stick, after making a transverse hole in the tube.
Step 4
Secure the elastic with threads about 20 cm from the bottom edge of the stick. At the same time, wind the thread with a width of 1 cm, since otherwise the elastic can quickly break.
Step 5
Glue a small cup out of colored paper.
Take a small stick, it will serve as the bottom of the glass and should move freely inside.
Step 6
Make a small groove around the side of the stick.
Lubricate the bottom of the glass with glue.
Insert the straw into the glass.
Step 7
Press the fastener with the threads along the groove.
Step 8
Attach the string to the bottom of the cup on one side and to the top of the tube, not far from where it attaches on the other.
Fill a glass with cooked confetti.
Step 9
Pull the lower end of the stick and release it sharply.
Enjoy the flight of confetti into the air. The flare gun is ready!
